DOOR

Filed Dec. 20, 1930 I INVENTOR W/LL/AM M GINDER. BY QZMAM' 2 M A TTORNE Y Patented Jan. 29, 1935 UNITED STATES DOOR William M. Ginder, Columbus, Ohio, assignor to The Kinnear Manufacturing Company, lumbus, Ohio, a. corporation of Ohio Application December 20, 1930, Serial No. 503,647

6 Claims.

My invention relates to doors and in particular to overhead doors.

It is the object of my invention to provide a hinge between the articulated sections of an overhead door which will not only perform the function of the hinge as a continuous hinge strut to reenfo-rce and align the sections of the door, but will also form a waterproof joint.

It is the object of my invention to provide a waterproof joint to guard against excessive wind pressure and to reduce the possibility of deflection and warpage.

It is also my object to provide a construction to facilitate the erection of the door.

Referring to the drawing, Figure 1 is a side elevation.

Figure 2 is the front elevation.

Figure 3 is the side elevation of the hinge with its guide wheel removed.

Figure 4 is a detailed section through the pintle pin, guide wheel and hinge.

Referring to the drawing in detail, 1 is a section of the articulated door and 2 is another similar section. The lower edge of the 'first section extends downwardly and outwardly as at 3 and the upper face of the lower section extends downwardly and outwardly to fit the surface 3 as at 4. The lower inside edge of the upper section is provided with a transverse plate 5 re- 30 tained on the vertical face of the section 6 by a plurality of bolts '7 and nuts 8.

Formed as an extension of the strip 5 is a laterally extending portion 9 which is formed in a curled lip or bearing 10. This curled lip or bearing receives a similar curled lip or bearing 11 of lesser section and telescopically arranged within the first mentioned bearing. This curled portion 11 is likewise provided with ahorizontally acting portion 12 and a transverse plate 13 which is mounted upon the face 14 of the lower door section 2 by similar bolts and nuts '7 and 8.

A hinge pintle pin may be inserted within each end of the curled portion 10 as at 15, the portion 11 being cut away at each end to receive the pin. It can be arranged against lateral movement by reason of the shoulder 16 engaging with the bracket 1'7 through which the pin 15 projects, such bracket being formed as a part of one of the plates 5 or 13, preferably 13. Upon the shouldered extension 16 may be mounted a guide wheel 18 on ball bearings 19. This wheel may reciprocate freely with its sleeve 20 or it may be retained by some suitable cotter pin not shown, according to the construction of the door.

I desire to comprehend within my invention such modifications as may be clearly embraced within my claims and the scope of my invention.

Having thus fully described my invention, what I claim is new and desire to secure by letters patent, is: v 5

1. In combination, a pair of superimposed door sections having abutting edges,transverse vertically disposed reenforcing plates extending across a portion of the faces of said sections adjacent said edges, and. laterally extending telescopically arranged hinge means mounted on said plates wherebysaid door sections can hinge on one another while said doors are reenforced adjacent their engagement with one another said lateral extensions being first horizontal and then downwardly curved.

2. In combination, a pair of superimposed door sections having abutting ends, adjacent transverse plates having right angular sections with telescopically arranged downwardly curled ends, the center of said curled ends being laterally displaced from the faces of said door sections, and the laterally extending portions being horizontal and parallel to one another while the plates are inalignment with one another in opposite di- 25 rections;

3. In an articulated door, an upper and lower door section, transverse reenforcing plates adjacent the juncture of said sections and extending across the sections, laterally extending telescopically arranged curved portions thereon forming a hinge, pintle pins in said hinge, a shouldered head on each of said pintle pins, and guide rollers mounted thereon,'said guide rollers and pintlepins being mounted at each end of the hinge and closing each end thereof.

4. In an articulated door, an upper and lower door section, transversereenforcing plates adjacent'the juncture of said sections, laterally extending telescopically arranged curved portions thereon forming a hinge, a pintle pin in said hinge, a shouldered head on said pintle'pin, and a guide roller mounted thereon, and a bracket on one of said plates interposed between the hinged portions of the plates and the shoulder of said pintle pin.

5. In combination, an upper and lower door section, a transverse upper and lower plate mounted on the respective sections and extending across the sections, said plateshaving interlocking curved portions to form a hinge, pins in said curved portions extending laterally thereof, and guide rollers mounted on said pins said pintlepins closing each end of said plates to prevent the entrance of dirt between the movable parts of said plates.

6. An overhead door structure, comprising an articulated door, lateral trackways for guiding said door between horizontal open and vertical closed positions, reinforcing plates extending completely across the faces of adjacent edges of adjacent sections of the articulated door,

transversely extending flanges on the adjacent edges of the reinforcing plates, said flanges having telescopically arranged curled ends forming hinges for the sections, and pintle pins inserted in said curled ends and carrying laterally disposed guide rollers for coaction with said 'trackways.
